Application filed. July 16, 1917.

To all whom it may concern:

-Be it known that I, BENJAMIN S. OLDB, aoitizen of the United States, residing at Madison, in the county of Dame and sconein, have invented new and useful Imp Machines, of which the following a speck fieation.

.M y invention relates to flliu'zbllltf; for mix Sing concrete and has for its object to pro" duce a machine of this shore-rotor of 521ml} capacity and. um. mm be n'ninuf- .tui'erl at low costlond is particularly upon the farm-and in connection operations.

' In the accompanying drawings Fig is a. side elevation, Fig. 2 a top plan n w. and Fig. 3 an end View of a concrete mixing; machine embodying my improve rents.

J1- Fig. tie a detail view illustrating the support. for one of the bearing rollers.

Fig. .5 is an end view of the yoke frame.

In the drawings indicate the side members of the supporting frame, which arepreferably X-sheped, and suitably braced as by theparts designated 3. In. this frame. supportd's'o us to be freely revolved about its. longitudi'riiil axis, is a container which is preferably wooden barrel 4, wet-er tight and of suitable strength. A bevel gear ring 5 is secured to the oiroumfv'enee o? the barrel, preferably a. little to one de oi center and toward its open end. The barrel is supported in a tilting frame mounted in ,the supporting frame of the machine. The tilting frame has a pair of trunnions Y-{Z that are adapted to lie in the erotches oi the upper portions of the X-sliuped side frames 2 2. where they are supported and turn, thus making it unnecessary to pi'o vide bearings for the trunnione, though the latter might be used under Circumstances rendering them desirable. The trunnions 3,18 supported or'carriedby plates B S't-o which aresecured a pair of r1ngs.9--9'. within which the barrel lies. "these rings are of suchsize that there is a free sneoe between them and the circumference of the barrel opposite where they lie. Secured to the peripheries of and uniting the rings 9-4) are a set of brackets 10 in which are mounted bearing rollers 11 adapted to en gage with the periphery of the barrel, and constituting the rolling supports therefor. There are preferably tour brackets and roll etw-two above and two below the bat rrel Specification of Letters Patent.

when. it is in working position. A yoke, constituting part ofthe swinging frame in which the mixing barrel is mounted, exthds rem-"ward from the ring 9 around the rear or {flog-ed end of the barrel, being formed preferably of n. mir of metal bars; suitably in f n-u; the yoke, and designated 5%, and 0. liver cross piece l3 uniting have. 'lhz; rmeslmr 13 is represented being; eured'to the yoke burs l2 l2 and th f poi-n1..- it limited. adjustment will be GUS ribed. A bearing 'Hiri of tlie l...rrel is :irnmged ems of rotation, and consistspreferably of e. sac et 14, secured to the cross piece 13 of the yoke of the tilting frame and emisieting of two separable parts, adapt ed to be dosed over the head or hell of a piece in, seceurerl to the bottom or closed l the herre The barrel. after having the .,-.n1' ring 5 s cured to it and the ball piece attached to its closed and, is inserted into the tilting frame. enters the socket it, the ring ooniee opt oslte the roller bearings 11, with the peripherul edge 6 of which they engage.

In order to re the barrel, coursing mixin. of. its eont'. lfemploy a bevel pinion 16 that engngt with the bevel rii'ig 5. It is mounted eh i: l? thot'extends o oi: trmmions i and, has see '21. to its outer end 21. Wheel 18 through which the power is applied to turn the shaft, a crank handle 19 being need for thispute pose when the machine to be hand-Oper for locking itfin three positions, onewith. the barrel with its discharge end upwardly inclined for mixing, another with the barrel substantially horizontal for loading, and a third with its discharge end downwardly inclined for delivering its contents. Thus in Fig. 1 the position the barrel will. occupy while being rotated for causing mixing is indicated by dotmjd-(lashlines, that which it occupies for discharging its contents by dotted lines, while full lines represent it as ones. through elote in.

\Vhen the ball 15' This bnris associatedlilll having its axis of rotation h0rizoI1tal--a' position well adapted for charging the barrel. The interior wall of the barrel will be provided with suitable agitating o mixing attachments as may be found desirable. The mixing vessel that I prefer to use in a machine such as I have described is an ordinary wooden barrel. The gear ring 5 is applied directly to the exterior of such barrel and performs three offices; 1t strengthens the barrel near its middle portion; it constitutes the gear ring through which ower is applied for rotating the mixing vessel' and it also serves as a bearing for the rollers, which therefore run upon a fairly true and cylindrical surface and do not engage with the surface of the barrel itself, which is more or less irregular and which in use would become rapidly Worn.

By making the ring member of the supporting yoke of the two parts 9 9 separated so as to be on opposite sides of the gear ring 5, I arrange for easily supporting the rollers 11 so that they engage directly with the ring 5, and make it possible to adjust them radially to insure proper contact with the surface 6 of the gear ring. This adjustment may be etfected by the use of liners 21 interposed between the brackets 10 and the ring members 9 9.

The crossbar 13, that carries the socket member of the ball-and-socket joint at the closed end of the mixing vessel 4, is adjustably connected with the yoke members 12 12' to which it is united so that the two parts, the ball member 15 and the socket into which it sets, may be easily brought into proper relationship before the crossbar carrying the socket -member is finally secured in place by means of the nuts 23.

By making the rear extension of the supporting yoke of the two parts 12 12 separated as shown, and carrying the crossbar 13, the adjustment just described, and the ready assembly of the members of the balland-socket support are facilitated.

A mixing machine constructed as described and as illustrated in the drawings may he made at relatively low cost, is not liable to get out'ot order, is substantial in construction and may be easily operated by one man. The mixing barrel or drum may be rotated, whatever its inclination incident to the adjustment of the tilting frame in which it is mounted, the drum being well balanced. due to the location of the bearings and the driving ring, as described and illus trated.

What I claim is:

1. In a mixing machine, a supporting frame, a rotatable mixing receptacle to the exterior of which is secured a bearing ring, a tilting frame in which is situated the mixing vessel, mounted in the supporting frame and comprising a pair of rings surrounding the mixing vessel adjacent to the said hearing ring and spaced apart. so as to lie on opposite sides thereofybrackts secured to the peripheries of and uniting the said rings, rollers supported in the brackets and extending between the rings of the tilting frame and into engagement with the hen ring ring, and means for rotating the mixing vessel.

2. in a mixing machine, a rotatable mixing vessel, :1 tilting frame comprising a ring portion within which the mixing vessel lies and turns, and a yoke extending across the closed end of the vessel, bearings mounted in the said ring for supporting the mixing vessel, a ball-and-socket bearing uniting the closed end of the vessel with the yoke and disposed approximately on the axis of 1'0- tation of the mixing vessel, means for adjustably uniting one member of the said hall-and-socket bearing with the yoke portion of the tilting frame whereby the parts of the said hearing may be easily brought into proper relationship after the mixing vessel is placed in the tilting frame, and means for rotating the vessel.
